Description
Calling conform and then unform with a spec that consists of some cat nested inside of some ? creates an extra level of nesting in the result:
(require '[clojure.spec :as s])
(let [spec (s/? (s/cat :foo #{:foo}))
initial [:foo]
conformed (s/conform spec initial)
unformed (s/unform spec conformed)]
[initial conformed unformed])
;;=> [[:foo] {:foo :foo} [(:foo)]]
This behavior does not occur with just ? or cat alone:
(let [spec (s/? #{:foo})]
(s/unform spec (s/conform spec [:foo])))
;;=> [:foo]
(let [spec (s/cat :foo #{:foo})]
(s/unform spec (s/conform spec [:foo])))
;;=> (:foo)
